For instance inputting to a list and finding longest streak of the same input python. It is not optimal (works in linear time O(n)) but i made some modification to your code (in Python 3): def longest_substring(s): length = len(s) if length == 0 : # Empty string return s final = s[0] for i in range (length-1): current = s[i] counter = i+1 while counter < length and ord(s[i]) <= ord(s[counter]): current += s[counter] counter +=1 Given a string s, the task is to find the maximum consecutive repeating character in the string. Below python code represents a small 'game': I flip a coin 100 times and get a sequence of Heads and Tails I try to figure out how many times in that sequence it happens that there are 6 Heads or 6 . Python Implementation: class Solution: def longest_consecutive (self The . Python: Selecting longest consecutive series of dates in list. You need to use dates[ix+len(l)-1] (note added -1) or you overshoot the end date (you don't notice this on sample data because sample data repeats the same date at the end of one streak and the beginning of the next, but if dates were unique, it would be wrong). I want to retain the longest sublist in which all dates are consecutive. From here, we have The longest streak. The idea behind this step is to get the start of the streak. Longest Consecutive Sequence. We will initialize a variable called currentLength and set it to 1. Note: We do not need to consider the overall count, but the count of repeating that appears in one place. You switched accounts on another tab or window. Tried doing it through for loop, but it gives only a total count, and through itertools. Let’s discuss different methods to do this in Python. But in previous questions the coding problem was described as a bit fuzzy. sign. ') return tossList. 1 ≤ t ≤ 10000. The alphabet set of the string is a-z. Skip to content.
